Specification of Letters Patent. Iatented Oct. 29, 1907 Application filed A rils, 1907. Serial No. 366.109.

v. 'tion of truckwheel'which shallbe almost noiseless and not injurious to the floors when made of tile or marble. Thisobject I accomplish by forming the wheel with ametsl hub upon ther'im of which annular'pulleys'of being formed-in sections and riveted or bolted in' place ,upon the hub. In my preferred form thesections of the vulcanized paper may be bolted or riveted together I and to a circumferential flange on the hub by transstood by reference to the drawings, in which:

Figure 1 is a side elevation of a truck wheel embody. ing my invention; Fig; 2 is a vertical cross sectional view of the same; and Fig. 3 is an elevation of a modi fication of my invention.- r

A is a cast iron hub and may be provided with a hole fitted, if desired, withvan axle B. This hub is formed with acential circular web which may be provided at the periphery with the lateral flanges (J, O and the .cir-

ably somewhat tapering outward as at D. The rim E of the wheel is'formed' of two or more circular sections oivulcaniz-ed paper oriiber as indicated at G, G, which are forced upon the tapered1flanges G, G. The inner lateral faces of the sections G, G, may be groovedas at 1 H so that when they abut they inclose the circumfer l ential flange E. Transverse rivets or bolts I are cmploycd to extend through the layers G and the flange E to clamp all of the parts firmly together and prevent The circumferential flange E may be notched as at e instead of having holes bored or cast in it to permit the rivets or bolts I to extend through in uniting the two sections of the rim- This construction also prevents the rim turning about, the hub should it from any cause become loosened. It is evident that while I ,employ two sections G, G of fiber, vin the case of small wheels, for light trucks only pne such section need be required as will be evident by reference to Fig. 3.

.50 It is evident that while I prefer to make the hub or central metallic portion open, for cheapncss and lightness,-it is immaterial to my invention. .The term them together and upon the hub.

lateral flanges used by mehare to be taken in a broad sense as comprehending the annular surfaces, tapered or otherwise upon which the fiber sections are secured. While I have shown my invention in the form I have found. most excellently adapted for commercial use,

nevertheless the minor details may be modified without'departing from the spirit of the invention.

Having 'now described my invention, what I claim as new and-desire to secure by Letters Patent, is:-

1. A truck wheel consisting of'a central metal hub having oppositely directed tapered flanges with the smallest diameters directed away from each other and largest diameters at the middle, combined with twonnnuiar fiber rim sections tightly sleeved upon the tapered flanges, and

transverse fastening devices extending through the sections for uniting them together and upon the hub.

2. A truck wheel consisting of a central metal hub having oppositely directed lateral tapered flanges and a circumferential central flange, combined with two annular fiber rim, sections tightly sleeved upon the tapered flanges and inclosing the circumferential flange. and transverse fastening devices extending through the sections for uniting 3. A truck wheel consisting of a central metal hub having oppositely directed lateral tapered flanges and a circumferential central flange, combined with two annular finer rim sections tightly sleeved upon the tapered flanges and inclosing the circumferential flange, and transverse .fastening devices extending through the sections and the circumferential flange for uniting them together and upon the hub. I

4. In a truck wheel the combination, of a central metal portion having two oppositely directed tapering portions and a central circumferential notched flange, with annularfiber rim sections tightly fitting the tapered portions, and transverse rivets extending through the rim sections and notches of the flange for holding the sections in position upon opposite sides of the flange.

5. In a" truck wheel the combination of n centralme'tal portion having two oppositely directed tapering portions and u central circumferential notched flange, with annular fiber rim sections tightly fitting the tapered portions and having undercut portions to receive the flange, and transverse rivets eitending through the rim sections and notches of the flange for holding the sections in position upon opposite sides of the flange andcornpletely inclosing' the flange.

6. In a truck wheel the combination of a central metal lic part having lateral annular portions and a circumferential flange, two annular fiber sections tightly fitting the annularportlons of the central part and inclosing the circumferential flange, and t ansvcrse}. rivets extending through the fiber sections and flange for uniting them to: gether.
